Where To Download Retroarch

Hey everyone, I'm a total novice when it comes to RetroPie and any kind of programming. I've run into a bit of a snag when it comes to a SNES game I've been playing, and I'd like to access my save state from the game on my laptop. The problem is, I'm not sure where my SNES save state files are actually located on my pi... I use a USB key to import roms to the pi, and I seem to only be able to access save states when the key is plugged into the pi - however, as you all know, the rom folder on the USB key doesn't seem to actually contain any folders for save states. Do the save states save to the micro sd card that I have in my pi at all times? To complicate things even more, I've never connected my pi to the internet (I don't have a long enough ethernet cable or wifi dongle atm); is it possible to remove/add save states from the pi without an internet connection?

Hello everyone!!! So ive installed emulation station on my laptop, a pi, and now my pc. My laptop and pc are running Linux Mint. The laptop and pi installs ran the playstation1 emulator with no problems. My pc install says im missing firmware scph5501. I found the file online and now i cant find the retroarch system folder to put it in. In my /home directory i only have Rotropie and Retropie-Setup folders. Any help is much appreciated.

Before you can use the cores you've downloaded in Retroarch, you need to set the path to the libraries in retroarch.cfg, the configuration file for Retroarch. Run Retroarch at least once to create a skeleton retroarch.cfg. By default, retroarch.cfg will be created in the directory $HOME/.config/retroarch, where $HOME is your home directory. If retroarch.cfg is not found at that location, run Retroarch and choose the Save Config option - Retroarch will save a new configuration file and display its path on screen. Alternatively, you can use the find command:

Once you've located the libretro cores, it's time to open retroarch.cfg using your editor of choice. Look for the option libretro_directory, which may be located near the bottom of the file. Insert the path to the libretro cores between the quotation marks on the right hand side. Assuming the cores are located in /usr/lib/libretro, the line in the configuration file should look like

RetroArch has a robust CLI for those who prefer the command line, there are also many pages which should have been installed by default for retroarch, retroarch-joyconfig and others. If you use the CLI be sure to configure your retroarch.cfg file before first use. This config is well commented so each option can be fully understood. Use retroarch-joyconfig command for simplified input setup. RetroArch can auto-detect inputs, which is a great feature to simplify playing with multiple/different controllers (refer to man retroarch-joyconfig for details). The retroarch.cfg file should be located in /etc/retroarch.cfg, your home folder or the directory where RetroArch was installed depending on your distro and compilation setup.

RetroArch creates memory card files for each individual game, in contrast to PCSX-R/ePSXe where all game saves are stored into 2 memory card files. To transfer memory card files from PCSX-R/ePSXe to RetroArch:

RetroArch supports loading audio DSP plugins to add effects such as reverb to the audio output. This has been in RetroArch for a long time, but was recently reworked to be easier to use and more accessible from the menu, and are available in the main RetroArch repository now. Now you can load DSP filters in the menu under Settings>Audio>Audio DSP Plugin, where you can load a DSP preset with .dsp extension, which is a text file similar to a shader preset that lets you chain DSP filters and specify their options. The DSP filters themselves are dynamic libraries that are loaded according to the .dsp file. Each DSP filter has a standalone preset that documents the default options, and there are some example presets that combine more than one filter.

Windows users with Nvidia hardware may find that even while idle, RetroArch CPU usage is upwards of 12% or above while using the GL video driver. If this is the case, go into the Nvidia Control Panel, and under Manage 3D Settings, check to see if the Threaded Optimizations option is set to Auto or On. If so, add retroarch.exe to the list of programs, and then toggle it to Off. This should lower CPU usage drastically.

The second method is to simply launch RetroArch from the command line in verbose logging mode, by doing retroarch --menu --verbose, and let it run for at least 4096 frames (about 1 minute at 60fps). When you close RetroArch, it will report the estimation results in the log. Again, running in exclusive fullscreen gives more accurate results. Example estimation output:

By default, RetroArch only writes SRAM onto disk when it exits without error, which means that there is a risk of losing save data when using crash-prone cores. To change this behavior, open ~/.config/retroarch/retroarch.cfg and set autosave_interval to n.

By default RetroArch searches for cores in ~/.config/retroarch/cores, which is where the Online Updater installs them. Cores installed with pacman are placed in /usr/lib/libretro and thus will not appear in RetroArch's GUI. You should choose one method of installing cores (pacman or the Online Updater) and change your configuration to match.

OVERRIDES. If you want to make a specific configuration that applies only to a certain emulator, emulated console, or game, you will want to use overrides. These are basically configuration (.cfg) files that are specific to a game or console. For example, if there is a certain game where you want to use a special hotkey or video scaling option, you would open up that game, make the adjustment in the settings, and then save it as a per-game override. Every other game will function normally, but the next time you boot that specific game, those per-game settings will load.

INDEPENDENT SAVES. Confusingly, there are a couple other options and configurations that work outside of the process above. This is because they are governed by their own configuration files, and not the typical retroarch.cfg or override cfg/rmp files mentioned above.

You could offload even more of your directories to custom folders as well, so that they were located somewhere independent of the default RetroArch folders. This is beneficial if you want to update RetroArch in the future while preserving your current setup. See the Updating RetroArch section below for more information.

Another way to update RetroArch is to do a manual reinstallation while preserving your most critical files. To do so, you would want to go into the Settings > Directory section and point some important folders to somewhere besides the default RetroArch folder. Here is the process:

By mistake I configured the keys in the MAME 2003 core completely wild, so that now nothing fits anymore. (Important: directly in the emulator, not in the retroarch interface).

Uninstalling and reinstalling the core did nothing. Is there a tip how I can reset the Core internal settings?

In AEL configuration there's a "Check retroarch BIOSes" option that if you point your Retroarch system directory to the place you copied the BIOSes to it checks them and in my case the checksums for what's expecting for PSX (5500, 5501 and 5502) match.

The only out of the ordinary thing was step 4 - once I got into retroarch gui my controller stopped working completely, and when trying my other input method (bluetooth mouse), only scroll wheel working - never mind, I connected a keyboard and hit escape to get out of retroarch gui.

I tried going again in retroarch using keyboard and went to the online updater and downloaded a few random things - after that rebooted and started emulationstation again - this time the game would start, I could hear the game sounds but the screen remained black, with the exception of a frame counter on the lower left that was incrementing continuously (not a frames-per-second but a frames-since-starting-the-game thing)

Note about the bioses: copied over all the files I had on RetroPie, don't know if the same ones are expected here. Maybe it's looking for slightly different names, or different case...is there a way to check retroarch is finding the expected ones?

And in regards to the bios, as long as you have not changed any configurations within retroarch you have placed them in the right place but you can check where retroarch is looking for them by looking for directories within the retroarch program once in directories the top one should be system/bios and it should point to /storage/emulators/bios.

The fact that RetroArch covers every video game system gives Android users a huge advantage. The available single-system emulators only cover the usual assortment of popular systems. There may be some instances where you'll have no choice but to use RetroArch.

These BIOS files are CASE SENSITIVE. Depending on which website you downloaded them from, they may be named differently. Make sure every BIOS is named exactly as you see it above. Speaking of where to download BIOS files, you can grab all of them below.

Depending on where you downloaded the game, an SBI file might already be included in it. If that's the case, simply make sure the SBI file and your PS1 ISO have the same name. If the SBI file isn't there with your PAL ISO, you can download a collection of all SBI files below.

I have tried copying the file LogitechLogitechCordlessRumblePad2.cfg to another file with the name of the joystick that appears in retroarch error message (without blank and special characters) and I also tried changing the name of the joystick inside the file. This was unsuccessful. Is there any documentation on how retroarch gets the joystick name (here: Logitech F710 Gamepad (DInput) (1133/49689)) and how I can map that name to a config file?

I have read somewhere in this forum that DInput does not work, but according to -logitech-f710-gamepad.html it seems DInput should work fine on Linux. Also DInput works perfectly in emulation station, mupen64plus, scummvm (and with jstest /dev/input/js0) and also works on my PCs (also Linux but on Intel) so it could also work for retroarch (in the worst case by using xboxdrv to expose it as xinput). e24fc04721
